Ver en Cuevana. A businesslike syndicate runs all the gambling joints in town; least profitable is honest Mike Lee's. Under pressure to allow cheating, Mike "walks out," leaving tough-minded daughter Lady Lee to earn a living the only way she knows. She soon becomes a success gambling among the rich, but, falling out with the syndicate, she considers the marriage proposal of blueblood Garry Madison. Can such a match work despite snobbery and old associations?
